[Bug 189368] Re: kernel panic with notebook Amilo Xa 2528 P5811 kernel 2.6.24

[Andy Whitcroft]

According to the upstream bug this is fixed by the upstream commit
below.  This commit appeared in v2.6.28 and therefore should be in the
current Jaunty kernels already:

    amd74xx: workaround unreliable AltStatus register for nVidia controllers
    
    It seems that on some nVidia controllers using AltStatus register
    can be unreliable so default to Status register if the PCI device
    is in Compatibility Mode.  In order to achieve this:
    
    * Add ide_pci_is_in_compatibility_mode() inline helper to <linux/ide.h>.
    
    * Add IDE_HFLAG_BROKEN_ALTSTATUS host flag and set it in amd74xx host
      driver for nVidia controllers in Compatibility Mode.
    
    * Teach actual_try_to_identify() and drive_is_ready() about the new flag.
    
    This fixes the regression caused by removal of CONFIG_IDEPCI_SHARE_IRQ
    config option in 2.6.25 and using AltStatus register unconditionally when
    available (kernel.org bugs #11659 and #10216).
    
    [ Moreover for CONFIG_IDEPCI_SHARE_IRQ=y (which is what most people
      and distributions use) it never worked correctly. ]
